Digital Wind Tunnel

Practical Stability Analysis

Since 1994 AeroLogic has been developing and refining PSW (Personal
Simulation Works). From the outset our goal has been to make Computational
Fluid Dynamics (CFD) tools and techniques available to aircraft and ship
designers who have limited budgets and personal computers (including laptops)
of average power.

Numerical solution - Cmarc (3D CFD using a low-order
panel method)

A fourth step for aeronautical applications involves repeatedly executing
the Cmarc analysis while varying several parameters, including yaw and
pitch angles and control surface deflections. This procedure is conducted
by DWT (Digital Wind Tunnel), which we offer as an option because
it is not needed by boat and surface-vehicle designers.

The following discussion concerns what this powerful analytical tool
does and how it does it.
